It is only necessary to perform the next step if more than 2 hours have
elapsed since a front-panel calibration of the microwave spectrum analyzer
has been performed.
The microwave spectrum analyzer should be allowed to warm up for at
least 30 minutes before proceeding.
5. P erform a front-panel calibration of the microwave spectrum analyzer by
performing the following steps:
Note that the following steps are for an HP 8566A/B microwave spectrum
analyzer , the steps may be dierent if you are using another microwave
spectrum analyzer .
